STOVEPIPB Filed March 30, 1929 Patented Dec. 31, 1929 UNITED STATES PATENT oFFicE STANLEY IE. JACKES, OF ST. LOUIS, MISSOURI, ASSIGNOB TO JAGKES-EVANS MANUFAC- TURING COMPANY, OF ST. LOUIS, MISSOURI, CORPORATION OF MISSOURI STOVEPIPIE Application filed March 30, 1929. Serial No. 351,392.

This invention relates to stovepipe, and with regard to certain more specific features to enameled and similarly decorated stove pipe.

Among the several objects of the invention may be noted theprovision of means for adapting standard lengths of enameled pipe to stoves positioned where at least one odd length of pipe is ordinarily required, this being done in such a manner" as to present a neat appearance; the provision of a device of the class described which eliminates any necessity for cutting the enameled pipe; and the provision of a device of the class described 5 which protects the enameled pipe and surrounding objects from excessive heat. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structure hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, in which is illustrated one of various possible embodiments of the invention,

Fig. l is a front elevation of a stove showing the invention applied thereto, parts be ing broken away for clarity;

Fig. 2 is a side elevation of Fig. 1, parts being broken away; and,

Fig. 3 is an enlarged side elevation of an enameled sleeve, parts being broken away.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring now nore particularly to Fig. 1, there is illustrated at numeral 1 a stove having a spaced enameled shell 2, the enameling being indicated by stippling. The stove is enameled for the purpose of improving its appearance and salability for living quarters, F but it has been found that the usual black iron stove pipe necessary for operation detracts seriously from the proper effect. Hence provision is made herein for using the more attractive enameled pipe. The difficulty in using enameled pipe is, however, as follows:

Ordinarily, black iron stove pipe is formed in standard sizes and lengths and as elbows and the like, which cannot be indefinitely multiplied in size and shape with profit. Hence ifthe distance between the smoke outlet'of a stove and a flue cannot be exactly met by any combination of standard lengths such as are provided commercially, it has been the custom of tinners to cut an odd length from a standard length of pipe in order to fill in the gap. This could readily be done with unenameled pipe.

On the other hand, when black iron pipe or the like is enameled at the factory, it is exceedingly difficult thereafter to cut the pipe to desired odd lengths, because the enameling dulls the cutting tool or prevents its action altogether. This also results in chipping the enamel if cutting is accomplished at all. Therefore if an odd length of pipe section is needed in any given installation,

that section has been left black heretofore, which of course resulted in an undesirable visual effect. As above described, most of the sections such as 9, 11, 13 and 15 of the connections 3 are of some standard size or length.

As forecast, standard lengths will not always makeup proper total length for a given con 'nection, so that an odd length such as 17 is often required, and inasmuch as this must be out by the tinner, it cannot be an enameled section such as are sections 9, 11, 13 and 15. It is understood that sections such as 17 are adapted to be readily cut in the usual way, being composed of the ordinary black, light Weight, sheet iron.

In order t-ohide the unsightly section 17, there is slipped over the enameled section 15 asleeve 19, which is shown in side elevation in Fig. 3. This sleeve 19 is enameled by the pipe manufacturer, inasmuch as it need never be cut subsequently. The length of the sleeve 19 is made as long as the longest odd section 17 that will ever be required with a given standard of length or lengths of sections such as 15.

Hence. it will be seen that the portions of the pipe which are enameled, are the standard length and/or size of sections such as 9, 11, 13 and 15 and also of the sleeve or collar 19.

None of these parts need ever be cut by the tinner or another who is installing the pipe. The only piece that the tinner needs to cut is the black iron adapter piece 17 which is subsequently hidden by the enameled sleeve 19, the latter being slipped down over the former, from a previous raised position (see dotted lines in Fig. 1).

It will be noted from Fig. 8 that the sleeve 17 comprises a cylindrical portion 19 with curved or turned-in ends 21. The purpose of the curved or turned-in ends is to properly align the sleeve 19 with the remainder of the stove pipe and maintain the space 23 shown in Fig. 2, which provides an insulating blanket of air around the adapter section 17. The reason for this blanket is that the part of the stove pipe which is most likely to become red hot, due to over-heating, is the section closest to the stove, namely, section 17. It makes no difference whether or not the black iron section 17 gets red hot, but it is preferable that enameled sections of pipe do not become red hot. Hence the enameled sleeve 19, which is at the part of the pipe most likely to become red hot, is protected from the heat by the insulating air pocket 23. That is to say, the enameled sleeve 19 does not become red hot because it is protected, and the other enameled sections do not ordinarily become red hot because they are at a greater distance from the stove.

It is to be understood that, although the edges of the sleeve 19 are shown rolled over as shown at numeral 25 (Fig. 3), a trimmed edge may be left or other edge means may be provided.

Another advantage is that the sleeve 19 prevents direct radiation from the red hot section 17 from. impinging on objects close to the stove, such as, for instance, the contiguous wall. Thus danger of fire and the like is reduced and an excessive radiation into the room is also prevented.

To recapitulate: the invention provides the advantage of a sightly pipe decoratively enameled through-out its length where exposed to view. Also, when the section 17 near the stove gets red hot (as it often does) the enameled section, which will not stand a red heat because the enamel will crack off, is protected by the insulating air space 23 between the enameled section 19 and black iron section 17. It is to be understood that the openings at the ends of the sleeve 19 are ample in diameter to pass over the beads 27 which are placed on the ordinary lengths of pipe for limiting the telescopic action at crimped and tapered portions such as shown at numeral 29.

It will be observed in Fig. 2 that the black iron section of pipe 17 is not provided with a head such as 27, so that there can be effected a close fit between the openings at the end of the sleeve 19 and the pipe itself.

which is variable in It will be appreciated that the person who is installing the pipe may have a supply of sections such as 17 which do not have beads and which he may cut to the odd lengths desired. The use of the headless section is herein set out by way of example merely, and it is to be understood that said section may be headed and the more loosely fitting type of decorated section 19 used. Furthermore, while the turned-in ends 21 provide a concentric air space such as herein described, yet this may be made eccentric to any desired degree. As stated, the sleeve 19 prevents any red hot radiation from the section 17 into the room or against contiguous objects.

It is to be understood that the sleeve 19 may cover a section equivalent to section 17 shape instead of round throughout; for instance, the section, 17 may be round at the top and elliptical at the bottom where it meets the neck 5 of the stove or where it meets any other length of pipe connected with said length 5.

Furthermore, the sleeve 19 may be made to cover any odd section such as 17 regardless of where positioned along the total length of the stove. pipe. If the length of stove pipe in question happens to be horizontal, no holding means is necessary to prevent longitudinal movement of the sleeve. If it is not horizontal it may be desirable to hold the sleeve 19 in place with a set screw or the like, that is, where the sleeve does not rest on something as is the case in the example shown in the drawings.

It will be seen that according to the example, the sleeve rests upon a portion of the stove at and below the neck or smoke outlet 5.

It is to be understood that this invention is not limited merely to enameled pipes, but any type of decorated pipe which cannot conveniently be out after decoration. The terms enameled and decorated are used synonomously herein.

In view of the above, it will be seen that the several objects of the invention are achieved and other adantageous results attained.

As many changes could be made in carrying out the above construct-ions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

1. A stove pipe comprising enameled sections, an unenameled section joining said enameled sections to a stove, and an enameled sleeve reaching from the stove to the enameled sections and covering the unenameled section.
